Checkbox [Parts Count also]
|
Indicates whether the device is made in China. If this checkbox is selected, the failure rate of the part is calculated based on Appendix A for the 299C Parts Count or Parts Stress model chosen.
|
|
Type
|
Choice List [Parts Count also]
|
Required only for the Memory subcategory.
The type of device. Many different choices are available including DRAM, EPROM, SRAM, and more.
|
|
Technology Type
|
Choice List [Parts Count also]
|
Not required for the following subcategories: GaAs MMIC and Linear.
The technology type of the device. Choices are:
• Bipolar
• CMOS
• Other MOS
|
|
Quality Level
|
Choice List [Parts Count also]
|
The appropriate quality screening level of the device. Accepted quality levels and values for general integrated circuits follow.
• A2 = 0.08
• A3 = 0.13
• A4 = 0.25
• B1 = 0.50
• B2 = 1.00
• C1 = 3.00

# of Bits
|
Integer [Parts Count also]
|
Required only for the following subcategories: EEPROM and Memory.
The number of bits in the memory device. This parameter is used in conjunction with Units to enter the memory device bits.
|
|
Units
|
Choice List [Parts Count also]
|
Required only for the following subcategories: EEPROM and Memory.
The units for the # of Bits value. Choices are:
• b (bits)
• kb (1024 bits)
• Mb (1,048,576 bits)
• Gb (1,073,741,824 bits)
You can enter the bits several ways. For a 1 kilobyte memory chip for example, you can type 1 for # of Bits and select kb for Units. Or, you can type 1024 for # of Bits and select b for Units.
|
|
# of Gates
|
Integer
|
Required only for the following subcategories: Logic, CGA or ASIC; and PAL, PLA.
The number of active gates in the package. You can determine the gate count from the logic diagram. A J-K or R-S flip flop is equivalent to 6 gates when used as part of an LSI circuit. For the purposes of a 299C prediction, a gate is considered to be any one of the following functions: AND, OR, exclusive OR, NAND, NOR, and inverter. When a logic diagram is not available, use device transistor count to determine gate count using the following equations:
• Bipolar: Gates = # of Transistors / 3
• CMOS: Gates = Gates = # of Transistors / 4
• All other MOS, except CMOS: Gates = # of Transistors / 3
